3. Specify an NBMA or P2MP
(unicast) neighbor and its DR
priority.

Configuring OSPFv3 route control

Configuration prerequisites

Before you configure OSPFv3 route control, complete the following tasks:
Configure IPv6 addresses for interfaces to ensure IPv6 connectivity between neighboring nodes.
•
Enable OSPFv3.
•

Configuring OSPFv3 route summarization

Route summarization enables an ABR or ASBR to summarize contiguous networks into a single network
and advertise it to other areas.
Configuring route summarization on an ABR
If contiguous network segments exist in an area, you can summarize them into one network segment on
the ABR. The ABR will advertise only the summary route. Any LSA on the specified network segment will
not be advertised, reducing the LSDB size in other areas.
To configure route summarization on an ABR:
Step
1. Enter system view.
2. Enter OSPFv3 view.
3. Enter OSPFv3 area view.
4. Configure route
summarization.
Configuring route summarization on an ASBR
This feature is available in Release 2406P03 and later versions.
Perform this task to enable an ASBR to summarize external routes within the specified address range into
a single route.
An ASBR can summarize routes in the following LSAs:
• Type-5 LSAs.
Type-7 LSAs in an NSSA area.
•
Type-5 LSAs translated by the ASBR (also an ABR) from Type-7 LSAs in an NSSA area.
•
If the ASBR (ABR) is not a translator, it cannot summarize routes in Type-5 LSAs translated from
Type-7 LSAs.
